2 Distributive Property
Week 1 Day 3 January 8th, 2014

3 Essential Question: Standards:
How do we use the distributive property to simplify expressions? Standards: A.SSE.1 Interpret expressions that represent a quantity in terms of its context. Interpret parts of an expression, such as terms, factors, and coefficients. Interpret complicated expressions by viewing one or more of their parts as a single entity.

4 Vocabulary The Distributive Property Term Coefficient Factor

5 The Distributive Property
The process of distributing the number on the outside of the parentheses to each term on the inside. Example 5(x + 7) 5 • x + 5 • 7 5x + 35

6 Examples 1. 5(2x+1) 2. -3(x +5) 3. 2 –3(x + 6) = 5(2x) + 5(1)

7 Which statement demonstrates the distributive property incorrectly?
3(x + y + z) = 3x + 3y + 3z (a + b) c = ac + bc 5(2 + 3x) = x 6(3k - 4) = 18k - 24 Answer Now

8 A term is a 1) number, 2) variable, or
3) a product / quotient of numbers and variables. Example 5 m 2x2

9 the numerical part of the term.
The coefficient is the numerical part of the term. Examples 1) 4a 4 2) y2 1 3)

10 Factor Factors are numbers you can multiply together to get another number: EX. 2 and 3 are factors of 6, because 2x3=6 In Algebra, factors are what you can multiply together to get an expression.

11 Try the following on your own
(3 – x) 2. -2(x + 4) +3 3. 2(x + 6 – 3)

12 1. 4 + 6(3 - x) 2. -2(x+4)+3 3. 2(x+ 6 – 3) = 4+ 6(3) - 6(x)

13 Homework 2x + 3(6x - 12) = 124 3x + 5(2x - 9) = 98
